abstract:The UltraSPARC is a microprocessor developed by Sun Microsystems which is now a part of Oracle Corporation and fabricated by Texas Instruments that implements the SPARC V9 instruction set architecture (ISA). It was introduced in mid-1995.
Intel already sells chips capable of simultaneous multi-threading, and Sun's UltraSparc IV chip, launched in February, incorporates both multiple cores and multi-threading.
